See: http://www.techrepublic.com/blog/linux-and-open-source/create-your-own-yum-repository/609/

  • Installing it

    • sudo yum install createrepo

  • Creating the repo:

    mkdir /var/ks/repo

    cd /var/ks/repo

    createrepo .

    • This will create a

NoSuchPackage: grub2

Manually adding grub2 and lvm to the %packages section, fixed this.

During installation on the target the installation process fails with a long list of issues Where this stands out:

NoSuchPackage: grub2

I've only found this page with it: https://bugzilla.redhat.com/show_bug.cgi?id=871143

Wont boot afterwards

Possibly be inspired by: http://www.redhat.com/archives/fedora-buildsys-list/2008-July/msg00062.html

  • boot from cdrom

  • choose troublshooting

  • rescue the image

  • cd /mnt/sysimage/var/log/anaconda

  • grep WARN anaconda.log

  • grep ERR anacondo.log

  • WARN anaconda: no kernel was installed -- bootloader config unchanged

  • ERR anaconda: unknown selinux state: None

Sites to look at:

Network boot

general network boot issues

the ks.cfg failed and states pressing ctrl-C will reboot the machine

alt-F2 will give you a command line prompt.

/tmp/anaconda.log will give you information on what has been going on so far.

Each of the %pre/%post scripts in the ks.cfg is stored, along with a log file in /tmp.

Asks admin to interactively select the NIC to use for install

Perhaps adding: ksdevice=bootif to the pxelinux.cfg file will help.

fedora 20 virtualbox unable to mount root fs on unknown-block

See below

vfs cannot open root device (null) or unknown-block(2,0)

'initrd=' was missing in the pxelinux.cfg boot command file.

HTTP/URL boot issues

redhat 6.1 fails to retrieve ks.cfg via http

For some reason 6.1 doesn't like to get the ks.cfg via http, but nfs works fine.

Post first boot

Kernel panic - not syncing: No working init found

Add: kernel.x86_64 To the package list in the kickstart file.

This seems to have occurred due to the inclusion of an i386 repo.

Starting init: /bin/sh exists but couldn't execute it (error -8)
Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

troubleshooting Network installation

KVM guest install network install

Source changed - please verify

The real issue, one of the packages can't be resolved. Start removing packages from the install list until it works. One of the anaconda tabs may explain why.

https://bugzilla.redhat.com/show_bug.cgi?id=1419945

  1. Installation source 4) [!] Software selection (http://10.1.2.3/images/rhe (Source changed - please l73) verify)

The path given in --location was different from the path given in 'url' in the ks.cfg

NoSuchGroup: core

Hope: I had generated a new repodata dir, I copied the original back in and hope this helps.

Running the command ends up with this anaconda error: NoSuchGroup: core
